Finding a function to model a road arch.

A wildlife corridor must be disnged to arch over a major highway. The arch over the highway is to be constructed in the shape fo a parabola. The highway is 8 m wide and will be centered under the parabolic arch. The arch must span a total width of 12 m at its base. The arch must provide a minumum cledarance of 4 m over the highway.

A) Describe the type of function that will be used to model the roadway arch dimensions.

You need to plug in various y and x values that you know are on the parabola. For example, you're told that the arch must span 12 m at the base. If you center the parabola on the y axis, then you know that the point (6,0) must be on the parabola. What other points do you know must be on the parabola?
